Looks like a Windows system… maybe this works:

out = dir

If your computer doesn’t have an ls command, you can do the same thing
from
Ruby with Dir.pwd

from Ruby with Dir.pwd

I guess you rather mean Dir.entries(‘.’) or Dir[“*”].

No, you have two other problems:

  1. cargo-culting example code for a different platform without
    understanding what it’s doing.

  2. running a system command from ruby without running that
    command from a shell to confirm that it works as expected.

Both should be pretty easy to fix :slight_smile:
